Evaluation of the Prospects of Adsorption Methods for Registration of Greenhouse Gases of Endogenous Origin

The adsorption was studied of methane (CH₄) and carbon dioxide (CO₂) on microporous adsorbents: activated carbons, Sorbonorit-4 and AUK, La-BTC metal–organic framework structure, and NaX zeolite. Adsorption isotherms of methane and carbon dioxide were obtained at pressures up to 0.12 MPa and temperatures of 213–333 K. Comparative analysis showed that the highest adsorption activity is exhibited by the AUK–CH₄ and NaX–CO₂ systems. The obtained results will allow us to analyze the main components of greenhouse gases using the method of selective adsorption separation and screening of surface gas composition, which is promising for conducting comprehensive studies of geodynamically active regions, including the Kamchatka Peninsula.
